Vonn will appear in a small part as Alicia, an administrative assistant, whose character provides a vital clue in a case about a terrorist threatening students in the season finale "Rubber Room." The scene, with Detectives Lupo (Jeremy Sisto) and Bernard (Anthony Anderson) and ADA Rubirosa (Alana de la Garza), will be shot on location in Brooklyn on Friday, April 9th. "Law & Order" Executive Producer Rene Balcer wrote and will direct the episode.

"Throughout Lindsey's remarkable Olympic experience, she was very supportive of �Law & Order' and has already been to the set as a visitor. We are glad that we can make her dream of appearing on the show come true," said creator/executive producer Dick Wolf.

Lindsey added, "I honestly couldn't be more excited about being on Law & Order. How many people get to appear on their favorite TV show?" Vonn recently became the first American woman to win the gold medal in downhill skiing at the 2010 Winter Olympics. She has also won three consecutive overall World Cup championships (2008, 2009, 2010), the first American woman and second woman ever to do so.

"Law & Order," now in its 20th season on NBC, airs Mondays at 10:00 p.m. ET and is a Universal Media Studios production in association with Wolf Films. Dick Wolf, Rene Balcer, Fred Berner and Peter Jankowski are executive producers.
